Hello.

  This patch removes obsolete PREFERRED_RELOAD_CLASS and 
PREFERRED_OUTPUT_RELOAD_CLASS macros from STORMY16 back end in the GCC and
introduces equivalent TARGET_PREFERRED_RELOAD_CLASS and 
TARGET_PREFERRED_OUTPUT_RELOAD_CLASS target hooks.


  Regression tested on xstormy16-unknown-elf.

  OK to install?

        * config/stormy16/stormy16.h (PREFERRED_RELOAD_CLASS,
        PREFERRED_OUTPUT_RELOAD_CLASS): Remove.
        * config/stormy16/stormy16-protos.h
        (xstormy16_preferred_reload_class): Remove.
        * config/stormy16/stormy16.c (xstormy16_preferred_reload_class): Make
        static. Change 'rclass' argument and return type to reg_class_t.
        (TARGET_PREFERRED_RELOAD_CLASS,
        TARGET_PREFERRED_OUTPUT_RELOAD_CLASS): Define.





Anatoly.
